Non-disponsable led lamp

ABSTRACT

A non-disposable LED lamp includes a main body, an LED unit disposed on the main body. The outer side of the LED unit is covered with a lampshade. A light-reflecting member is vertically provided in the lampshade. The light-reflecting member has a periphery side formed with a light-reflecting slanted surface which is taped toward the LED unit. When the LEDs is activated, part of the light will be reflected by the light-reflecting slanted surface to radiate light toward the whole lampshade, so the non-disposable LED lamp enables to radiate light in a pantoscopic way. The non-disposable LED lamp of the present invention can increase the radiating angle to provide an even illumination effect.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to non-disposable LED lamp.

2. Description of the Prior Art

LED is widely used on an illumination apparatus because it has lowworking voltage, a long life span, and no mercury pollution, instead oflight bulbs and fluorescent lamps. As shown in FIG. 1, a conventionalLED light bulb comprises a main body 1, an LED unit 2 coupled to themain body 1, and a lampshade 3 connected to an outer side of the LEDunit. When the conventional LED light bulb is electrified, the LED unit2 radiates light and the light penetrates through the lampshade 3 toachieve an illumination effect.

Referring to FIG. 1, the rays of the LEDs are direct light, so theradiating angle is small and the light is concentrated. Thus, when theconventional LED light bulb is electrified, the rays of the LED unit 2are only toward the front of the lampshade 3, so there is no light tothe sides and rear of the lampshade 3. The conventional LED light bulbis unable to provide an even illumination. Accordingly, the inventor ofthe present invention has devoted himself based on his many years ofpractical experiences to solve this problem.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide anon-disposable LED lamp which can radiate in a pantascopic way toprovide even illumination.

In order to achieve the aforesaid object, the non-disposable LED lamp ofthe present invention comprises a main body, an LED unit, a lampshadeand a light-reflecting member. The LED unit is disposed on the mainbody. The lampshade is used to cover an outer side of the LED unit. Thelight-reflecting member is vertically disposed in the lampshade. Thelight-reflecting member has a periphery side formed with alight-reflecting slanted surface which is taped toward the LED unit.

When the non-disposable LED lamp of the present invention is switchedon, the LEDs of the LED unit will illuminate. The rays of light aretoward the light-reflecting member. Because the lampshade is providedwith the light-reflecting member and the light-reflecting member has thelight-reflecting slanted surface, part of the light will be reflected bythe light-reflecting slanted surface to radiate toward the wholelampshade, so the non-disposable LED lamp enables to radiate light in apantoscopic way. Thus, the non-disposable LED lamp of the presentinvention can increase the radiating angle to provide an evenillumination effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way ofexample only, with reference to the accompanying drawings.

As shown in FIG. 2 through FIG. 4, the non-disposable LED lamp 100according to a preferred embodiment of the present invention comprises amain body 10, an LED unit 20, a lampshade 30, and a light-reflectingmember 40.

The main body 10 comprises a connecting head 11 to connect acorresponding lamp socket (not shown in the drawings), such as E27 lampsocket or MR16 lamp socket. In this embodiment, the connecting head 11is adapted for E27 lamp socket. One end of the connecting head 11 isaxially formed with a bearing part 12. The bearing part 12 comprises twometallic casings 121 which are connected through a connecting member122. A gap a is defined between the two metallic casings 121. In theembodiment, the bearing part 12 is constituted by the two metalliccasings 121 which are integrally formed with a connecting plate to formthe connecting member 122.

The LED unit 20 is disposed on the main body 10. In this embodiment, theLED unit 20 comprises a circuit board 21 which is fixed to the bearingpart 12. The circuit board 21 has a plurality of LEDs 22 thereon. TheLED unit 20 further has a driving module 23. The driving module 23 iselectrically connected between the connecting head 11 of the main body10 and the circuit board 21 for activating the LEDs 22 to illuminate.

The lampshade 30 is used to cover an outer side of the LED unit 20. Oneend of the lampshade 30, opposite the LED unit 20, has a through hole31.

The light-reflecting member 40 is vertically disposed in the lampshade30. One end of the light-reflecting member 40 is a fixed end 41. Thefixed end 41 is tapered toward the lampshade 30 to form a rhombus-likeshape. The fixed end 41 has an end surface with a lock hole 42corresponding to the through hole 31. A lock member 50, such as a bolt,is inserted through the through hole 31 and locked to the lock hole 42,such that the light-reflecting member 40 is secured to the inner wall ofthe lampshade 30. Another end of the light-reflecting member 40 is afree end 43 which is taped toward the LED unit 20. The free end 41 has aperiphery side formed with a light-reflecting slanted surface 43.

FIG. 5 is a schematic view of the preferred embodiment of the presentinvention when in use. When the non-disposable LED lamp 100 is switchedon, the LEDs 22 of the LED unit 20 will illuminate. The light rays aretoward the light-reflecting member 40. Because the lampshade 30 isprovided with the light-reflecting member 40 and the light-reflectingmember 40 has the light-reflecting slanted surface 44, part of the lightwill be reflected by the light-reflecting slanted surface 44 to radiatetoward the whole lampshade 30, so the non-disposable LED lamp 100enables to radiate light in a pantoscopic way. According to a real test,the maximum radiating angle of the conventional LED light bulb is about180 degrees. The maximum radiating angle of the non-disposable LED lamp100 of the present invention is about 270 degrees. Thus, thenon-disposable LED lamp 100 of the present invention can increase theradiating angle to provide an even illumination effect.

It is noted that the fixed end 41 of the light-reflecting member 40 istapered toward the lampshade 30 to form a rhombus-like shape to decreaselight shadow on the lampshade 30 projected by the light-reflectingmember 40, so it is not easy to find the existence of thelight-reflecting member 40.

It is noted that the bearing part 12 of the main body 10 is constitutedby the two metallic casings 121 which are connected through theconnecting member 122 and between the metallic casings 121 is the gap a.This can greatly increase the area of the bearing part 12 to contact airso as to radiate heat from the LEDs 22, so the LEDs 22 can avoid thermalrurnway.

FIG. 6 is a sectional view according to another embodiment of thepresent invention, which is substantially similar to the aforesaidembodiment with the exceptions described hereinafter. Thelight-reflecting slanted surface 44 of the light-reflecting member 40 isprovided with a light-reflecting layer 45, such as a chromate treatmentlayer, to enhance the light-reflecting capability of thelight-reflecting slanted surface 44. The connecting member 122 of themain body 10 has a plurality of radiating holes 123 and a partition 13is provided in the gap 1 to enhance the radiating capability of thebearing part 12, such that the LED unit 20 can be provided more LEDs 22or to increase the power of the LEDs 22 to enhance illumination effect.
